Specification of Letters Patent.

SELF-ACTING WATER-BALANCE.

Application filed April 20, 1911. Serial No. 622,330.

To all whom it may concern:

Be it known that I, MIGUEL subject of the King of Spain, residing atBarcelona, Spain, have invented certain new and useful Improvements inSelf-Acting ater-Balances; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

y invention relates to improvements in self-acting water balances, inwhich the weight exerts a pressure upon the liquid contained in a vesseland causes said liquid to flow into a tube which communicates with amanometer or with a vertical tube wherein the liquid rises until theequilibrium level is reached, when the weight of the body may be read ona graduated scale.

The invention consists in arranging the lLLoBn'r, a

, cylinder and the piston loosely fitted into view of one another and inlocating therebetween an elastic vessel, filled in with liquid,incommunication with the vertical column which marks the weight on agraduated scale.

The invention further consists in certain combinations of leverstotransmit to the liquid the pressure exercised by the body to beweighed.

With these, and other objects in view the invention consists in thenovel details of construction and combinations of parts more fullyhereinafter disclosed and particularly pointed out in the -elaims.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all theviews :Figure 1 is a longitudinal view partly in elevation and partly insection of the apparatus complete; Fig. 2 is a top plan Fig. 1 with theplatform removed, and taken on the line 22 thereof; and Fig. 3 is adetail transverse sectional view taken on the line 3-3 of Fig.

Referring to the apparatus in detail, A designates a suitable casingprovided at either end thereof with 1 supports B for mounting the scaleplatform or plate 1. Said plate is provided on the underside and andwater tight cates witli'the'column 14.- of a manometer D at either endwith forks 2, engaging with the arms 3 ofthe levers 21 and 22. Each ofsaid levers has the arms 3 thereof connected by a bar 3*, which ismounted on blocks C, and by means of which said levers are fulcrumed.The levers 21 and 22 engage with a ring 23, which surrounds said leversas illustrated in Fig. 3. At the points of engaging with said ring, thelevers are eachv provided with a spur 24:, that contact with said ringat'opposite ends, and which, by reason of their small bearing surfaces,have relatively little friction with said ring. A cylinder 9 open at oneend is mounted on the base of the casing A, and has loosely workingtherein a piston Sprovided with a piston rod 19, that s adapted to beengaged y a member-19 carried by the lever 22 adjacent the free endthereof. Within the cylinder 9.is located a vessel 12 having elasticwalls, and which communithrough the medium of a tube 13. It isto beunderstood, of course, that the collapsible vessel 12 is designed tocontain a liquid which through the weight of the platform 1 is caused tomove in the graduated column 14 of the manometer.

It is obvious that those skilled in the art may vary the details ofconstruction and arrangement of parts without departing from the spiritof my invention, and therefore 1 do not wish to be limited to suchfeatures except as may be required by the claims.

I claim 1. In an vautomatic water balance, the combination of acylinder, a iston mounted in the cylinder, a collapsib e vessel filledwith a liquid and arranged in the cylinder, a manometer connected to thecollapsible Vessel, a rod projecting from the piston, a pair of leverspivotally supported at one of their ends, supported on said rod, a ringconnectin the other lever to the first lever, and a plat orm carried bythe levers for sustaining a weight, substantially as described.

2. In an automatic water balance, the combination of a cylinder, acollapsible vesone of the levers being pivot-ally Patented Jane 18,1912.
